Juul | Frost Architects have designed a minimalistic and yet characteristic bollard by combining the slim, cylindric shape with asymmetry and light in opposite directions. Focus is also on efficiency and uniformity, even with long distance between the bollards. The secondary backward light adds to a pleasant atmosphere by its glowing effect on the surrounding.
